The Dolmabahce Mosque was constructed under the patronage of Bezmi Alem Valide Sultan, the mother of Sultan Abdulmecid, and was completed in 1855 after the Sultan's death. The mosque was designed by Garabet Balyan and is officially named Bezmialem Valide Sultan but earned the name Dolmabahce Mosque due to its proximity to the palace.
The mosque is known for its two slender minarets and its massive vaults with windows that support its dome from four sides. The interior of the mosque is adorned with baroque decorations. Its most striking feature is the circular arrangement of huge windows, which had never been attempted before. This design allows light to enter from the Bosphorus, resulting in an awe-inspiring interior.
The mosque's courtyard and fountain, which are typically seen in all Sultan mosques, were unfortunately removed to make way for road expansion works. In 1956-60, the mosque was used as a Maritime Museum but was later repaired and reopened for worship in 1967.
